Some solid picks here! It sounds like the general consensus is to start with a light, free tool for simple mistakes, but keep the heavy-duty paid software in your back pocket for actual hardware scares. I’m going to go ahead and pin this for anyone else panic-searching at 2 AM. Just a final reminder: the best recovery software is a solid backup routine! Closing this thread out for now—thanks for the input, everyone.
Recuva is fine for the basics, but if you’re dealing with a partition that’s gone RAW or a drive that’s actually failing, you usually have to step up to the big leagues. I’ve had the best luck with tools like Stellar Data Recovery or EaseUS. They are paid, yeah, but the deep scan capabilities are on a different level. I once recovered a 2TB external drive that my PC wouldn’t even recognize using those—definitely worth the license fee for the peace of mind.
Hello! New to NAS but am looking forward to regaining ownership of my data. I purchased a used DXP4800 Plus and am shopping for drives, but I have no idea how best to set this up.
I’m primarily looking to horde as many shows, movies, photos, videos etc. as I can. Ideally I want 20+TB drives but I can only afford 2-3 big drives right now.
Needs:
Maximize storage capacity
Easy expansion in the future
My confusion is mostly with how to set up RAID in a way that is both cost-efficient and not wasteful of storage.
If I get 3 drives, my only option is RAID 5, which I understand is strongly discouraged for large drives due to the risk of data loss.
If I get 2 drives, I would need to buy 2 more in the future and switch to RAID 6/10, losing half my storage for protection
Is RAID 5 really that bad for big drives? Would it be better to forgo RAID entirely, back up any critical files to another device, and accept the data loss if a drive fails?
Honestly, for a quick and free fix, I always start with Recuva. It’s not the most “surgical” tool out there, but for accidentally hitting Shift+Delete on a folder of photos, it’s saved my skin more than once. It’s super lightweight and doesn’t try to upsell you every five seconds, which I appreciate.
Hi. I am running my TS464 with one 12TB disk. It is not enough so I plan to buy 2 more and end up with 24TB in RAID5.
From my perspective I see two ways of doing that:
Insert first new disk -> convert single drive to RAID1 -> insert second new disk -> convert RAID1 to RAID5.
Insert both new disks and create empty RAID1 pool from them -> copy data from single drive to RAID1 -> convert RAID1 to RAID5 using source disk as third one.
Way 2 imo seems better because during some time of the process I will still have backup on source drive, also one RAID conversion instead of two, so I would say less points of failure?
But I am not storage expert therefore if You have any advice I will read them carefully.
Regards.
When I first configured my DS220+, I assigned my two 4Tb drives into a single RAID1 storage pool and single (max size) Btrfs volume. I’m using about 35% of available space.
I now know that was a big mistake as I now have a desire for a second volume to serve as an off-site Hyper Backup for a friend.
I’ve done my reading and found the following…
RAID1 storage pools can’t be changed to SHR storage pools
The volume size on RAID1 (or SHR?) storage pools can’t be reduced to make room for another volume.
It is possible to change a RAID 1 storage pool with a single Btrfs volume into multiple Btrfs volumes ONLY if there is unassigned space in the storage pool or larger drive are installed.
If the above is true, I’m stuck with only two options: Buy (2) larger drives, or rebuild the storage pool from scratch. Since I have plenty (65%) of unused space, the second option seems practical.
I do have an external 4Tb HDD purchased as a backup. And I do run regular USB Hyper Backups to it. So, theoretically, I can rebuild the storage pool from scratch.
The steps should/could be as follows:
Mount all shared drives if not already mounted
Create a new Hyper Backup of all Folders and Packages
Create new System Configuration Backup
Factory Reset NAS
Set Storage Pool as SHR
Set multiple volumes as required
Install Hyper Backup package
Restore Data and Packages from Hyper Backup to desired volume
Restore System Configuration from Backup
So, here are my questions:
Is my understanding of storage pool and volume limitations correct?
When restoring from Hyper Backup, do I have the option to restore “system configurations”?
I have read elsewhere that it is better to restore a System Configuration from backup that is not part of Hyper Backup. Is this true? And would this be the last step or before Hyper Backup restore?
Hello, I woke up this morning to my pfSense box down. I tested each of the components and determined it was the board. I have a second same board onhand and have replaced it with all the components back in the way they were with the former board.
I set the BIOS back to AHCI as ZFS RAID1 is configured.
Upon startup I get the following:
F1 ?
F2 FreeBSD
F5 Drive 1
F6 PXE
Boot: F5
F1 ?
F2 FreeBSD
F5 Drive 2
F6 PXE
Boot: F2 ###############################################…continuously…
Is this a rebuild or is the system dead?
I did backup my entire configuration after the last change but I always hold my breath when restoring. I presume this route would require simply installing pfSense again, configuring the LAN/WAN and then restoring from the past backup?
Please advise if the continuous ############## is a rebuild or if the above manual reinstall is the way to go. Thank you.
I am on Fedora Linux, and I was organising files to move to optical media. This is a BTRFS RAID 1 filesystem with FDE, which is shared via NFS. The permissions for this area are nobody:nobody.
I had the NFS share mounted on my laptop and was in admin mode within Nautilus (Fedora Workstation), and wanted to rename the folders, which has several files within them. After renaming (e.g. 25G-BD1 to BDR1) when I went to look at the folder, it was empty, much to my shock.
I am not sure why this happened exactly, but I can only think that the rename is essentially a move execution for the folder, and the files did not follow, maybe due to the permissions. Again, this confuses me – I was performing these process as “admin” which I suppose is just superuser and not actually root.
I later found out that doing such things over NFS within Nautilus isn’t a good idea, with permissions set as they are on the server – probably for this reason.
So I unmounted the NFS from the laptop, unmounted the disks from the server to stop as much activity as I could, and pray the CoW holds true.
As I thought about what my options were, I first looked at using testdisk but it was advised not to, and look at using BTRFS tools to recover, but I couldn’t remove/delete one mirror disk which I needed as a lifeboat to store and image of the remaining disk. BTRFS tools would not permit a removal of one half of a RAID 1 array. And I could not delete either as it would migrate back to the remaining disk, thereby causing rewrites.
So I was stuck. I needed another solution. Then I found about Hetman RAID Recovery. So I tried it out and it found the folders (and files) on the disk.
Before I went to consider a licence, I then stumbled on this reddit and realised not only did I miss out on a free licence giveaway a month or two ago, but you apparently are offering a free licence for The Partition Recovery – which as I understand it will do the job for a a single target disk from a RAID 1, and that the RAID Recovery is for more complex RAID arrays.
Needless to say, I have learnt a lesson here. I laugh at the irony that I lost my backups that I wanted to backup further (to cold storage).
I would greatly appreciate a key to restore my files. I luckily have a 1TB SDD free to restore this data to, before moving them back onto the array.
I won’t be doing what I did again, I thought it was a convenience to do things remotely but now I realise that with sensitive data I should really be on site at the server.
Thank you!
I got suggested (Synology AI) to make a full hyper backup, but this requires a C@ subscription or a second NAS…
Starting the docker containers causes a file checksum mismatch on a docker container file, and Volume1 becoming readonly.
Preventing to start of the docker containers, prevents triggering the file mismatch, and so keeping a rw RW Volume1
During backup I have some multiple other file checksum mismatches on file which did not trigger a Volume1 becoming readonly (and I have some older backups)
Volume1 is hybrid raid with 1 drive fault tolerance btrfs 5.2 TB 3.3 TB free. And is scrubbed.
So 2 slots in my 4 bay system
3rd slot is empty, and 4th slot is for video surveillance recording ext4-fs.
Surveillance package stopped for now.
Both Volumes and all 3 drives reports Healthy.
Volume1 has 2 WD60EFRX-68L0BN1 6TB
Having 2 new HDDs:
Seagate IronWolf ST6000VN006 6TB
How to replace the Volume1 HDDs?
What is the best way?
1)Take them both out and replace by new? But what about user shares etc….
Can I put back the old volume! as disc3&4 and copy the data to the new Volume?
2)Turn off, Replace one, turn on, rebuild, turn off, replace the other, turn on, rebuild
3)Add a hot spare in the free slot 3, …
replace first and rebuild?
make second (old) hot spare?
4)
…???
Hi guys – I’ve run a NAS system for a few months with in a Jonsbo N3 case, CWWK Q670-NAS 8 bay motherboard, Intel i9- 14900K CPU and 48Gb of Crucial DDR5 memory.
It started giving me some errors on one of the CPU cores so I started to troubleshoot. I rebooted to Memtest and ran that for a while with no errors.
Then I booted to a Linux bistro so I could run OCCT which also ran ok with no errors – I was running a test using Prime95 when the system just shutdown immediately. Since then I have replaced the PSU, CPU and motherboard and nothing works. The system simple clicks once, the PSU, CPU and system fans all spin up for a second and then stop and nothing else happens.
I’m at a complete loss as to what to try next.
Please can someone give me a pointer or two….
Crashed volume and one bad sector are observed in the Storage Manager for DS212, WD60EFZX, SHR/EXT4 (no data protection). At the same time diagnostic software (WD Kitfox) shows no errors or remapped sectors (at least after one full surface test pass). Is it possible to fix the volume without recreating it? Thanks.
Hi – I am in a bit of a sticky situation and am hoping someone can help me out. I have a 4 bay DS418Play NAS with all 4 bays in use. I had set it up as SHR1 but after one of my drives crashed, I replaced with a new one. However soon after that, the new drive crashed as well. I figured my NAS is falling apart and i need to buy a new one, so i shut the NAS down while waiting to buy a new NAS. 2 days later, i needed access to a file urgently on my NAS so i turned it on and downloaded my file, but my NAS suddenly restarted and after restart I had another drive showing up as crashed. So now I have 2 drives crashed out of 4… and after the restart when I tried to access my data in the NAS, i could not see any data in the NAS 🙁. But i feel certain that the data is not lost in the drives and it is the NAS which has caused the drives to crash. But i am not sure how to recover my data safely. I have not turned on my NAS since that day yet. How can i recover my data or rebuild the NAS (or transfer to a new NAS) with minimal risk of loss of data? I would like to avoid giving my drives to someone else (e.g. a professional) if possible for privacy reasons.
I accidentally deleted a folder and also emptied the Recycle Bin before realizing it had my project files.
Is there any method to recover permanently deleted files in Windows 10/11?
